2018 Honda Accord FORWARD COLLISION AVOIDANCE

Extended highway driving(500+miles). Collision Mitigation Problem continues to show as alert in dash. Does seem to reset when vehicle turned off and back on but this is not a new problem and a major reason for purchase

The contact owns a 2018 Honda Accord. The contact stated that while driving 35 MPH, the Forward Collision Avoidance sensor activated independently, causing the vehicle to stall. The contact stated that the brake warning light was illuminated. The contact was able to continue driving to his destination. The contact called the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was 55,593.

While driving 35mph and accelerating, emergency braking system deployed. The lights on the dash and audible beeps presented simultaneously. There were no other cars on the road other than a parked vehicle off to the drivers side. Vehicle slowed to around 5mph before releasing. No accident occurred. Honda dealership stated no active recalls were noted and an appointment would take several weeks based on the labor shortages.

The contact owns a 2018 Honda Accord. The contact stated that while driving at various speeds, the Forward Collision Avoidance feature engaged without incident with the brakes warning light flashing on the instrument panel. The contact had taken the vehicle to a dealer however, the mechanic was unable to duplicate the failure. The manufacturer was notified of the failure and a case was filed. The vehicle was not repaired. The failure mileage was approximately 23,000.

I had taken my vehicle in to dealership on multiple occasions for the vehicle stating “road departure mitigation system problem” multiple times and every time I was told there wasn’t an issue. Eventually the system completely stopped working and the dealership wanted to charge me over $3,000 because I was about 5,000 miles over warranty. I never fixed it. 2 years it hasn’t worked until one day my car randomly braked on its own as the system just started working out of no where almost causing an accident. Thankfully no one hit me from behind. But then it yet again isn’t working. Seems a default that continues to happen. And I’m worried it will happen again with my child in the back and someone slamming into me due to a system issue on the vehicle. I also included other errors that have occurred with this same issue but it goes away and didn’t happen as often as the collision mitigation issue. I put 2 months ago because that’s when the car randomly braked on me while driving on a busy road and that system is suppose to be “out” not working at all. But this all happened over 2 years ago when it went out and dealer said I didn’t need it for my vehicle to work correctly. dealership has all paperwork for everytime I took in the vehicle to have it looked at for this

I got a Collision Mitigation Braking System warning while driving at a high speed > 60 mph on the Interstate with adaptive cruise control turned on. The system suddenly cuts off speed and lost cruise control. I have to stop on road side, turn off the car and restart it for the warning go away.

The car’s Collision Mitigation system stops working for no reason, causing me to completely lose my cruise control until I can turn off the car and restart it. This has happened in stop-and-go traffic on the Interstate while the car is under the control of the adaptive cruise control as well as while driving down the road with absolutely no other cars around me. Suddenly the system cuts off and the Collision Mitigation Warning message comes on. The Honda dealership has no response to this. I have had the car since September 2021, and this occurs approximately 3 times per month.

Four incidents of car braking on its own. Three on highway and one in town. On highway no other vehicle was near us.

Collision Mitigation braking system has engaged several times while driving in the city and Highway when there are no obstructions. Speeds vary from 35mph to 60mph.

Quite simply we were driving through a construction zone that was down to one lane with monitored traffic. My wife was driving and approaching a steel plate in the road that was laid on top of existing asphalt. While slowing down to move over the plate at a slower rate of speed the automatic breaking brought the car to an unnecessary stop almost causing a collision from behind. This was super scary and alarming. Will this happen if we are going 35, 55, 70 mph?

Driving down at approximately 20-30 mph on a clear day. Vehicle in front of me was turning left and I was going straight so I veered right. Vehicle turns on orange brake sign on dash and suddenly pressed the brakes full stop. Good thing no one was behind me. Automatic braking can only be turned off via a physical button on left side and changing settings on dash. This is a frequent problem that happends atleast ones a month.

I had owned a 2018 Honda Accord which I had purchased in 2019. I had owned the car for about 6 months when the situation occurred. I had been about 30-50 before a railroad track and had already slowed down to 30-35 mph at this point. My dash lit up with the word 'brake' and the brakes went on automatically. There was nothing in front of me but the approaching train track which shouldn't set off the sensing function. I had a truck behind me which thankfully didn't hit me although he did blare his horn at me due to the unexpected braking. I went home and started looking online to see if other honda owners had similar experiences. There were stories from driving down the freeway going 70+ mph and having the same issue with nothing in front of them and coming to a complete stop to people having accidents because of the braking issues, etc. The next day, I called Honda and they stated that they were aware of the issues but were not planning on issuing a recall. I called the dealership and spoke to the manager and stated that I was going to return the car that day. He asked if they could check out the brake situation and I stated if Honda knows of the issue but is not planning a recall, then what is the mechanic at the dealership going to fix? I declined his offer and returned the car that evening. When I got to the dealership, the manager wouldn't even come and face me, which was another issue. I sunk money into a faulty car that I will never see back. I went to a different dealership and bought a different brand of car. To this day, if I see another Honda in front of me while driving, I let off of the gas because knowing the braking issue that I had, I don't want to be involved in an accident if they other Honda driver has braking issues.

The vehicle gave me a warning for the emergency breaking and began to aggressively brake for no reason. This has happened to me three separate times. Case 1: There were no cars in front of me, a few cars behind but not too close. The vehicle slammed on the breaks from ~50mph to ~25mph aggressively. Thankfully I was not hit, only received a few angry honks from other drivers. Case 2: Driving on the highway at 60-65mph, vehicle slowed down to 30-35mph or so, i was afraid i was going to end up in the hospital if i caused a wreck. Cars were around in other lanes and nobody was in front of me in the 2nd lane. I got off the highway to take a few deep breaths, called the Honda Dealership in Ferndale, Michigan. Dropped my car off a few times to get it looked at, the service department was "unable to duplicate the event" and sent me on my way. I work in front camera modules/windshields releasing at another automotive company so i have experience with this item. I asked for my case to be forwarded to an engineer at honda to help explain the situation and to be connected to them, no luck. Case 3 similar to case 1, but a busier road. Distance was kept from vehicle in front, but my vehicle still decided to "break-check" the car behind me. This was a close one. Now, I typically drive the vehicle with the auto braking feature off (it may not be completely off but i turned it off from the steering wheel menu options). I own a 2018 Honda Accord EX-L 2.0t. All these cases happened around 28,000miles-40,000miles (two of three cases under warranty, vehicle was taken in 2-3 times during warranty and the last time the dearlership didn't even consider trying to find out the issue once they saw my history of already bringing it in). The front camera module camera void on the windshield was clean and clear 3of3 times, the grille had some dirt/residue 1of3 times which is what the dealership blamed it on. I have received no support for my claims, hence I am reporting it here. Disappointed...

The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

My 2018 Honda Accord brake automatically when it’s nothing in front of me, this has happen 3 times without any car in front of me.The car behind me like to hit me because my car put on brakes automatically.

Three times now I have been driving with no obstructions in front of me and the Automatic Emergency Braking System has flashed "BRAKE" on the dash and then slammed the brakes on. One of the times, I was on the freeway going approximately 60 mph. Everything on the seat next to me went flying and my seatbelt locked, hurting me (I did not see a doctor as it was not necessary). There were no cars or obstructions in front of me. This could have caused a bad accident had someone been behind me at the time. The other two times, people were able to brake in time so as to not cause an accident. This was terrifying. I took it to our local Honda dealership and they simply said everything looks fine and maybe the sensor was dirty. My car was clean at the time on the freeway, and I don't recall if it was the other two times. I did not have my insurance or police look over the car as there was no accident and no need to contact them. But the actual dealership DID look over the car. It all happened suddenly with no warning and no need. The only "warning lamp" was it flashing "BRAKE" on the dash immediately before it slammed on the brakes each time.

When driving on the freeway (>50mph) with no obstacles visible in front of me, the Forward Collision System will occasionally cause the HUD to rapidly flash and warn me to “BRAKE”. It will display this message for a couple of seconds before disappearing. I have noticed that this has a higher chance of occurring when I am driving towards the sun.

My vehicle has activated the collision avoidance/emergency braking on numerous occasions for no reason. I have taken it to my local Honda dealer for this problem, and since they cannot recreate it, they claim there is no problem. It generally happens when there are lines in the road, or a change in the color or the road surface. It happened again last week while I was traveling on US 301 near Maxville Fl. There is road resurfacing going on, therefore one lane is a lighter asphalt, and the other lane is dark. I was going about 60 mph, changed lanes, and the car slammed on the brakes and displayed the brake warning on the instrument panel. Fortunately, no one was behind me. This is the typical behavior of the car when it happens

On four different occasions vehicle applied the brakes on it’s own while changing lanes. as if there was a hazard in front, however there were no vehicles in front of my vehicle.

I was driving on interstate behind line of trucks in construction zone at 55mph. It was raining lightly. When zone ended, I pulled into left lane and accelerated to 70 mph. A semi truck in right lane pulled in front of me, I braked to avoid hitting it. I got within 1-2 car length of semi and suddenly car braked on its own. Brakes fully locked up. I tried to accelerate after car slowed a lot (down 15-20 mph) and considerable distance opened up between us. Car would not allow me to regain ability to accelerate. Car brakes remained locked up until car slid to complete stop in left lane. Car then allowed me to again accelerate. Unknown if braking indicator activated. No trouble lights were illuminated. Almost hit by vehicle behind that had to maneuver to avoid. Have noticed other issues where brakes briefly automatically apply when passing large vehicle in right lane. This seems to be happening more frequently in past year.

I am getting warnings of brake system problems including electric parking brake problem says it’s not available, brake hold system problem,brake performance reduced. Adaptive cruise control system problem, collision mitigation problem, and road departure mitigation problem. The car has slowed down on me while on the highway and side streets even when I am trying to accelerate and if I push the pedal all the way down it feels like it is fighting to stop, I’m afraid I am going to get hit from behind due to this. I just brought the car into the dealer for the recalls and mentioned these issues I initially thought the errors codes were maybe due to how cold it’s been because the entire screen also shut off on me then restarted its self minutes later. This car only has 30,000 miles on it.

Routine and ongoing false and nuisance braking warnings from collision mitigation system. Triggering of the warning is presumably a precursor to erroneous activation of automatic braking.

Driving at 70 mph on interstate 74 in cruise control the vehicle automatically braked on its own nearly causing a rear end collision by the semi following. Vehicle then proceeded to de-rate down to 40 mph and would not accelerate beyond this causing us to drive down the highway with our hazards on over an hour home. Additionally, after making it home every warning lights for adaptive cruise control, collision mitigation, power steering assist, lane keep assist, etc. continue to come on and off. Vehicle was just at the local Honda dealership where they did a recalibration, to which I just picked up and within 10 miles of driving the vehicle every warning light is back in and vehicle de-rated again. Vehicle is very unsafe to drive and at this point a danger to myself, family and others on the road.

Going about 10mph down a side street when emergency brake automatically caused my car to stop but nothing was in front of me. Car came to a complete abrupt stop which jolted me forward, but then resumed driving like normal. Yes available for inspection as it has not been taken in or inspected for this problem, it only happened once. No warning message prior. If this would have happened on a busy street, it could have easily caused an accident.

Breaks came on for no apparent reason and put vehicle into a side ways skid. Lane Landed up in meridian .
